Ep 6. Secret History of Mercury

In this episode of How the Universe Works, entitled "Secret History of Mercury," viewers are taken on a journey to explore the smallest planet in our solar system like never before. Mercury has often been ignored or overlooked by scientists due to its proximity to the sun and the challenges that presents for observation and exploration. However, recent discoveries and advancements in technology have shed new light on this mysterious planet.

The episode begins by discussing some of the early observations and theories about Mercury, including the belief that it had an atmosphere and might even be home to life. However, as scientists began studying Mercury more closely, they discovered that the planet's proximity to the sun made it inhospitable for life as we know it. Instead, they found a barren, rocky landscape with extreme temperatures and a magnetic field unlike any other planet in our solar system.

Despite these challenges, scientists have continued to study Mercury in order to learn more about the early history and formation of our solar system. The episode explores some of the latest discoveries, including evidence of water ice at the planet's poles and the possibility of volatile compounds on its surface. By studying Mercury's composition and geological features, scientists hope to gain a better understanding of how the solar system formed and evolved over time.

The episode also delves into some of the latest breakthroughs in space technology that have allowed scientists to explore Mercury more closely than ever before. Viewers will learn about the MESSENGER spacecraft, which was launched in 2004 and spent several years orbiting Mercury, collecting data and images of the planet's surface. The episode also features interviews with scientists who are working on new missions to Mercury, including the upcoming BepiColombo mission, which will launch in 2022 and aim to study the planet's interior and magnetic field in greater detail.

Throughout the episode, viewers are treated to stunning visuals of Mercury's surface and landscapes, including craters, mountains, and valleys. Experts also share their insights on what these features can tell us about the planet's geological history and the forces that shaped its surface over billions of years. Overall, "Secret History of Mercury" is a fascinating look at one of the least-understood planets in our solar system and the cutting-edge science and technology that is helping us learn more about it.

As the episode concludes, viewers will have a newfound appreciation for Mercury and the incredible discoveries that have been made about this planet in recent years. From volcanic activity to water ice, the mysteries of Mercury are slowly being unraveled, and scientists continue to reveal surprising insights about the planet's history and evolution. Whether you're a space enthusiast or simply curious about our solar system, "Secret History of Mercury" is a must-see episode of How the Universe Works.
